Question

我正在尝试为灯箱创建模糊的背景效果，并且滤镜模糊css不起作用，而是使整个灯箱模糊。

任何帮助将不胜感激。

我的代码不是CSS的javascript，而且在不模糊前景的情况下似乎无法正常工作。

我已经尝试过模糊滤镜，并且我认为单击灯箱图像后，这不适用于页面。

在问问者明确表示他想要其他东西之后添加

如果要使整个背景模糊，则需要更改HTML结构。由于您对:target伪元素做出反应以显示灯箱，因此您需要让元素对所示的灯箱做出反应，然后跟随灯箱以使用general siblings combinator ~。因此，所有灯箱必须在.container元素之前，并且.container元素是模糊的，如果在定位之前有.lightbox。

.container {
  width: 100%;
  margin-top: 6px;
  display: inline-block;
  text-align: center;
  text-decoration: none;
  transition: filter .3s linear;
}

.small {
  height: 180px;
  width: 320px;
  position: relative;
  margin-top: 3px;
  margin-bottom: 3px;
  transition: 0.6s ease;
  filter: brightness(95%);
}

.small:hover {
  transform: scale(1.03);
  transition: 0.15s ease;
  opacity: 1;
  -moz-opacity: 100%;
  -webkit-opacity: 100%;
  filter: brightness(100%);
}

.lightbox {

这不是问询者想要的您只需要将模糊滤镜限制为图像即可。因此，

.lightbox {
  /* ... */
  filter: blur(5px);
}

执行此操作

.lightbox img {
  /* ... */
  filter: blur(5px);
}

.container
{
